<h2>RNA Polymerase</h2>

Explanation:

RNA polymerase, a chemical in the cell, is answerable for making mRNA from the right quality. RNA polymerase is like DNA polymerase, yet it makes a RNA strand as opposed to a DNA strand. The promoter region of DNA Helix is attached by RNA polymerase.

It pulls in nucleotides that supplement those on the DNA strand containing the gene of interest. RNA polymerase duplicates one strand of DNA to make a stretching bit of singlestranded mRNA. RNA polymerase makes the mRNA strand in what is known as the 5' to 3' course.

<h2>Answer:</h2>

The correct answer is option A which is an abnormal male with nondisjunction.

<h3>Explanation:</h3>

The karytope is the complete picture of chromosomes present in a cell of an individual.

It is used to study the chromosome number and abnormalities related with chromosome numbers.

Chromosomal nondisjunction is the consequence when the homologous chromosomes are not completely separated from each other during meiosis.

While chromosomal translocation is the crossing over of genetic material between two chromosomes.

Only chromosomal disjunction can be seen from the karyotype.

Answer:

e. Mitochondrial

Explanation:

This is a case of mitochondrial heredity so correct answer is e. Mitochondrial
In this case, the mother transfers her mitochondria to her children. So the child is affected. The male does not pass this trait on to his children.
We can see from the lineage that the mother has defective mitochondria so all their children will have defective mitochondria. One of his sons has mitochondrial, but is unable to pass it on to the next generation.
